Hi Nico,
I actually ended up using this code (from the link you provided yesterday) and it worked perfectly. Thanks so much for all of your help!

Hi Nick,
I’m unable to use the events widget, because I want to be able to provide the feed to our partner organizations for them to display links to our events on their websites. Those sites use WordPress too – is there a way for me to somehow connect our calendar feed to their sites (so the events and content would still be on our site, but a dynamic feed would appear in a widget on theirs?)

[jkennedy]

Hi Nico,
So for example when I drop the rss feed you used above into my RSS widget on the homepage of my calendar, the events are out of order with the furthest away event on top. Check out the ACT/SAT deadlines section on the homepage of http://www.cfwvconnect.com/community-calendar for an example.

That worked perfectly – thank you so much!
